replacing appliances with energy star ones

17 years ago

I thought I saw a thread on this, but I can't find it so I will start one.

We are buying a new fridge (our really, really old one is broken). So our new one will be energy star.

This got me thinking about our dishwasher, that doesn't work very well, so I either do things by hand or wash them 2x. It works better some days. Would it be best to replace this dishwasher with a new energy star one although I have to throw something out that isn't exactly broken?

Also, the new dishwashers say they use less energy than doing dishes by hand. Can that really be true? I don't mind doing dishes by hand, but if this is true, then it would be smarter to use a dishwasher AND I would save time.

We have a gas water heater. I don't know if that makes a difference. Do these dishwasher heat water themselves or get hot water from our water heater??

I also have to add that it has been extremely frusterating finding a "normal" sized fridge to replace our old one. Fridges are so much larger than they once were! Then we find a small fridge and find out they (manufacturer) don't bother to apply for energy star ratings because the smaller fridges don't use as much energy as the big fridges. Ya, well, Regardless of the size, I want it to be as efficient as possible, dugh!

You may want to have your dishwasher checked out. Maybe a filter or something is clogged and water isn't spraying the way it should. With that said, I stopped using my dishwasher years ago. Like you, I don't mind doing them by hand, but I also discovered since I started heating my water on the stove to around 160-70 degrees, I only need about 1/3 the amount I used to use. Very hot water cleans much better. Must use rubber gloves though.

I know my dishwasher didn't heat the water, but maybe some do.

I think you still have to be careful about that energy star rating. A long time ago, I saw some news report about how some appliances are rated that way, but really don't meet the standards. Sorry, I can't remember any other details.

The water does get hot in the dishwasher. It is just very old, so I bet it never really worked well. It may be like 20 yrs old. Our fridge is a westinghouse, and I bet the dishwasher was bought at a similar time

I do use hot water to hand wash, and gloves. Our stove is gas and so is our water heater so heating the water on the stove wouldn't save money.

I assume they say dishwashers cost less to use than handwashing because we use alot of water to rinse the dishes when we wash them by hand?

February 25, 2010 2:36 PM CST Appliance Cash for Clunkers set for March debut by Bob Geiger Staff Writer And you thought Cash for Clunkers was dead. Come March 1, a home appliance version of the stimulus program that provided cash to car-buyers trading in their old models is scheduled to start. Designed to save consumers money for buying energy-efficient clothes washers, dishwashers, freezers and refrigerators, nearly $5 million in federal stimulus funding is designed to help Minnesota households save up to $200 for replacing their aging appliance with a qualifying Energy Star model. The Minnesota Trade-in & Save Appliance Rebate Program, operated through the Minnesota Department of CommerceÂs Office of Energy Security (OES), could enable up to 25,000 Minnesota households buy Energy Star appliances. WarnersÂ Stellian on Wednesday held a media event with OES and Waste Management Inc. officials to publicize the program. Just like Cash for Clunkers, residents are encouraged to decommission appliances that consume more energy. Eligible appliance and rebate amounts are clothes washers, $200; dishwashers, $150; refrigerators (minimum of 7.75 cubic feet priced over $300), $100 to $200; and freezers, $50 or $100. Advertisement WarnersÂ Stellian is not the only OES partner involved in the program. Other utilities or retailers partnering for the energy-efficient appliance replacement effort are Sears Holdings Corp., Best Buy Co. Inc., Whirlpool Corp., BSH Home Appliances, Great River Energy and Minnesota Power. Here is a link that might be useful: Finance & Commerce

Appliance puzzle - which old ones to use and which to replace

Are you doing a total renovation? If so, the decision about whether to go with a 48" range (or any stand-alone range) or separate cooktop + wall ovens is a fundamental one which will impact the entire cabinet design, and must be decided very early in the process. If you have the desire, space, and budget for a 48 incher, I'd insist upon it, as one cannot be easily retrofitted into any kitchen when/if the existing cooktop dies. It's perfectly OK to economize by re-using a fridge and dishwasher, as the holes they occupy are standard and new ones can be easily popped in when the old ones die. But cooktops are different. There are no standards for shape/size between brands so matching a new one to an existing cut-out in your counter tops can really limit your choices down the road. Can you get Hubs to buy into these arguments?

In NC, they seemed to have a decent system. The retailer had to log in on the state webpage to see the funds available and enter the amount. They get the rebate directly, and it comes off our paid price. There was $8.8 million and there is still some left, although almost half the money was used the first day, so that's a little bit surprising. Sales started Thursday and end today. Compared to other states, we had a pretty good rebate, 15% off energy star fridges, freezers, clothes washers, and DW's. Now we'll just have to wait for our fridge.

Most new dishwashers do use less water than washing dishes by hand. Mine (an ASKO, from Sweden) uses less than five gallons to do a dishload. Given that a kitchen faucet can deliver 2.2 gallons per minute at full force in a house with strong water pressure, even using the water at half-flow in your house means every minute of running the faucet is at least a gallon of water. So you've got five minutes to wash a dishwasherload full of dishes. :-)

Most of the high-end (typically European) dishwashers also heat their own water. Some will heat water as hot as 170 degrees, allowing you to leave your water heater at a lower level.

Why leave the water running for rinsing? Just have a separate pan of rinse water.

"use less energy than doing dishes by hand"

If the poster is really asking about using less energy, washing dishes by hand can't be beat.

I use the rinse water to fill my wash side of the sink.
so, that rinse water is used 2x, once to rinse and then a second time to wash the dishes.
I do not fill up a rinse bucket because of this.
However, I do have a full sink of water by the end of hand washing. I bet that is at least five gallons. If I can fill up a washer full of dishes and use only five gallons for that, I would end up saving because A full dishwasher is maybe 3 sessions of hand washing. We usually only use the dishwasher every other day or so. So, I can see a dishwasher saving water and money used to heat the water, however, It still uses electricity to run.

The newest dishwashers do use less water and thus save energy, but be advised that this can mean they take longer to wash than dishwashers in the past. Just an FYI
